Voting technology today has not addressed the issues that disabled voters are confronted with at the polls. Because approximately 17% of the voting population is disabled, their issues should be handled with a solution geared towards their needs. Disabled voters need to be able to cast their vote without the assistance of others. The Prime III multimodal voting system [2] addresses these issues. This demonstration will illustrate the use of the Prime III system, a virtual reality (VR) version (Prime V), and a similar version created using a voice user interface (VUI).
In this paper six novel Dielectric Resonator Antennas (DRAs) providing Circular Polarization (CP) using single probe feeds are proposed. By splitting the fundamental mode of conventional rectangular or cylindrical DRA...

The presence of cyclic dependency calls in integration testing is a major problem to determine an order of classes to be tested. We proposed an approach to solve this problem. Hence, this paper proposes a class ordering tool (CO Tool) for integration testing based on our approach for finding a test order using object-oriented slicing technique. Our approach breaks cycles by slicing classes for partial testing, whereas many researchers delete relationships to break cycles and create stub to represent interactions of testing between classes. Therefore, the benefit of our approach is to decrease the cost of implementing test stubs.
As the communication technology weighs heavily in the power system, so the security issues becomes major concerns. So far most security research has focused on the SCADA system. In this paper we consider the security ...

Three intrusion detection systems that use trails of system calls have been investigated. The three techniques used to generate the pattern database have been adapted from sequence method, lookahead-pairs method and variablelength-with-overlap-relationship method. Testing against Trojan horse and denial of service attacks was analyzed. None of the systems is capable of defeating the system-call denial-of-service-attack. Modification is necessary to indicate maximum threshold value for the number of times a pattern may be contiguously repeated. Furthermore, Lookahead-pairs method had the best space cost performance with a window size less than 24.

In recent years a huge number of online auctions that use Multi Agent systems have been created. As a result there are numerous auctions that provide the same product. In this case each customer can buy a product with the lowest possible price. But searching between auctions in terms of finding the suitable product can be time consuming for consumers and also providing products in different markets is a difficult task for suppliers. So the need for an autonomous agent in these types of markets is deeply felt. On the other side the structure of an auction mechanism that provides the environment for traders to operate their trades is vital. Despite all the research that has been done about online auctions, most of them were about single markets. But in real world the stocks and commodities of companies are listed and traded in different markets. There is a growing tendency towards research about online auctions and Market Design. Particularly in recent years CAT (CATallactics) game has provided an important opportunity to develop and test new techniques in this field. In this paper after introducing CAT game and PersianCAT agent, we want to challenge the conventional accepting policy used in stock markets like New York Stock Exchange and provide a better solution that improves the general performance of the markets.

The purpose of this pilot study was to explore the feasibility of using hand drawn images to identify symbol components for incorporation into warning symbol design software. This software will use an interactive evolutionary computation (IEC) algorithm to generate and evolve symbols mathematically described by a set of numerical parameters. Therefore, participants (N = 100) ages 19-43 (x = 23.2) were recruited to determine these symbol design parameters. Participants were invited to hand draw warning symbols for three referents: fall from elevation, hearing protection, and hazardous atmosphere. A panel of design engineers determined 27 attributes were present in the fall from elevation, 19 in the hearing protection, and 25 in the hazardous atmosphere images. A direct clustering algorithm was used to determine which attributes, or symbol parameters, were most commonly present or conspicuously absent among the clustered image families. For the fall from elevation, hearing protection and hazardous atmosphere referents, the clustering algorithm identified six, four and four symbol parameters, respectively, primarily responsible for distinguishing one drawn symbol from another. Thus, these parameters will be included as evolvable genes in the IEC software.
